    Shear stress problem
    --------------------------------------------------------------------------------
    My answer to question 5 is wrong, can you correct? PCD = pitch circle diameter

    Factor of safety = ultimate tensile stress / safe working stress

    I find two essential and one secondary errors in your text:

    (1) In your sentence "If PCD meant the diameter to start with this shear stress is 2 kN m / 200 mm ...". The error is that you divided the torque by the DIAMETER.
    The correct formula ...

    Solution Summary

    A shear stress problem for pitch circle diameters are determined.
